1 Application
ClimaticControl-HC is developed for variable flow temperature control in heating and cooling systems particular
in low-temperature installations like floor heating and cooling systems. The flow temperature is controlled de-
pending of the outside temperature following a curve.
Using the ClimaticControl-HC the operation of a water floor system can be adapted to the actual demands of
the system. In particular, the control can be used in apartments where users have their own individual living
habits. A room temperature thermostat can also be connected. The control has a 7-day programmer including
9 factory set programs and 4 user defined programs.
The control is normally used in conjunction with a hydraulic control unit which includes circulation pumps, a
two- or three-waymixing valve and a valve actuator.
The ClimaticControl-HC has been designed for use in dry environments, e.g. in residential rooms, office spaces
and industrial facilities.
Verify that the installation complies with existing regulations before operation to ensure proper use of the instal-
lation.

5 Installation and Electrical connections
5.1 ClimaticControl-HC Installation
The ClimaticControl-HC can be installed directly on a solid base (e.g. a wall). For this purpose the front panel of the
ClimaticControl-HC must be removed (fig. 4a) and the back section should be fastened using appropriate screws
and pins (these are not included in the scope of supply) (fig 4b) Fix the climatic control HC on a plane surface
(wall…)
If the ClimaticControl-HC has been factory fitted with cables for connecting to a pump, valve drive, temperature
limiter, sensors etc., take care not to damage or crack the cables during the installation. Furthermore these cables
should not subjected to any tensile stress during installation. The cables will be fixed by means of the device for
strain relief at the ClimaticControl-HC.
If the ClimaticControl-HC is delivered together with a hydraulic control unit (for example FRG or FlowBox) and if it is
not attached to that unit by any installation plate or support, it should be installed next to that unit.
Pay attention to the correct connection of the cables if the ClimaticControl-HC is not installed directly on a hydraulic
control unit but at some other place for the reason of better access.
Refer to the directions about this in section 5.2 Electric connections.

5.3 Room Temperature –Direct Plug In
As an option you can plug in a room thermostat to the ClimaticControl-HC. Direct plug in of a room thermostat op-
timizes the operational time of the circulation pump and even the supply flow temperature depending on the condi-
tions in the main room.
5.3.1 Mixed circuit (Water Floor), standard room thermostat, wired type
If a wired type of a standard room thermostat is plugged in and the preset room temperature is reached in
the room, the under floor circulation pump switches off after pump delaytime. (PUMP: System parame-
ters: pump delay time)

5.3.3 Wireless room thermostat (Water Floor thermostat “trF1”)
With WFHT-RF (BASIC, LCD or MILUX)
WFHT-RF BASIC WFHT-RF LCDMILUX-RF-xxx MILUX-RF-Hygrostat
Only RF thermostats from the WFHT-RF series or the MILUX-RF series can
be used together with an active antenna 433,92 or 868MHz.
The MILUX-RF Hygrostat can be used only with the 433,92Mhz frequency
RF thermostat initialization to the Controller:
SYSTEM PARAMETERS MENU, section
RADIO-CONFIGURATION with RF room thermostat
fig.8
If a radio frequencyroom thermostat is plugged in, the flow temperature calculated on the basis of outdoor
temperature and the curve (= flow temperature preset value) is optimized depending on the main room tempera-
ture.
The offset value is calculated in the following way:
Adjustment = preset value of supplied temperature + (room temperature - actual value) хcompen-
sation offset
(Compensation offset: System parameters: “tr1o”Flow temperature offset for “trF1”)
Example 1: preset calculated value of flow temp. = 35 °C; room temperature: preset value = 21 °C,
actual value = 19 °C; offset (tr1o) = 1,5
Estimation 1: 35 °C + (21 °C –19 °C) × 1,5K =>> flow temperature increased by 3,0K to 38 °C
Example 2: preset value of flow temperature = 35 °C; room temperature: preset value = 21 °C,
actual value = 22 °C; offset (tr1o) = 1,5
Estimation 2: 35 °C + (21 °C –22 °C) × 1,5K =>> flow temperature decreased by 1,5K to 33,5 °C
The pump will be switched off when room temperature will be 1°C upper the setting temperature
of the thermostat.
5.3.4 Wireless room Hygrostat (Water Floor thermostat “trF1”)
If a radio frequencyroom Hygrostat is plugged in, the flow temperature calculated on the basis of outdoor
temperature and the curve (= flow temperature preset value) is optimized depending on the main room
temperature. (See the previous part for more explanation)
The working mode (Heating or Cooling) of the installation could be managed by the end user directly on
the room hygrostat. (See the MILUX humidityleaflet for more explanation)
The residual humidity will be supervised by the MILUX-RF hygrostat in the house. If humidity is
detected the
“Wcal“temperature will be increased by step of 0.1°C/minute to avoid a too cold water on the hydraulic
circuit and risk of condensation in the house.
5.3.5 Wireless RF room thermostat (High temperature circuit thermostat “trF2”)
If a second circulation pump is installed and managed by the ClimaticControl-HC (Inst: System param-
eters: installation type, “2P.x”), you can install a second radio frequency room thermostat to supervise the
working of the high temperature pump.
This pump will work in the following way: If the preset room temerature is reached the High water
temperature circulation pump switches off after pump delay time. (PUMP: System parameters: pump
delay time)
Note: Only a standard room thermostat could be installed on the second circuit.
Ex: WFHT-RF (BASIC, LCD or MILUX).

5.4 Wireless RF outside sensor (Inst: System parameters: Input, “OUSE”).
As an option you can plug in a wireless RF outside sensor room thermostat to the ClimaticControl-HC. This solu-
tion is very interesting in rehabilitation, to avoid wires trough the wall, in a building management with several CC-
HC, in this case only one outside sensor can be installed to manage all the building.
WIRELESS OUTSIDE
SENSOR
The wireless outside sensor can be used only with the 433,92Mhz frequency
RF outside sensor initialization to the Controller:
SYSTEM PARAMETERS MENU, section
(Inst: System parameters: “OUSE”)
fig.9
Radio alarm: RF supervising function.
If the ClimaticControl-HCis installed with RF thermostat(s) and there is no radio signal received during more than 2
hours, a display alarm will be activated,the backlight and the small RF antenna logo radio will blink.
1. To stop the alarm, maintain the (OK) button pressed for about 10 seconds.
2. Check the batteries of the RF thermostat(s) or outside RF sensor. Please replace them if exhaust-
ed.
3. Check the position in which the antenna was installed. It must be installed in vertical position.
Installation in or on a metal body can abate the power of radio transmission. Minimize the distance
to the RF thermostat.
If radio alarm is displayed:
- Due to the wireless thermostat, the regulation will continue to work as an installation without thermostat (no com-
pensation).
- Due to the Wireless outside sensor, the regulation will continue to work with the last value received from the out-
side sensor.
5.5 Inputs functions (In1 & In2)
If no wired thermostat is installed in the house, you will have the possibilityto use the two available inputs of your
ClimaticControl-HCfor different functions (Inst: System parameters: Input, “In1 & In2”).
5.5.1 Input1
Inst: System parameters: Input, “HC”
You could use the input 1 to connect the an external signal which give the Heating or Coling working mode
of the installation (This signal could be done directly by a reversible input).
Inst: System parameters: Input, “Aqu”
1/ You could use the input 1 to connect the an imersion thermostat witch schould be placed in a storage
tank. In Heating mode this immersion thermostat will be use to switch off the circulation pump (Pump1) to
avoid cold water circulation in the circuit if the storage tank is discharged. (This solution is generally use
when solid wood burner is installed)
2/ You could also use this input to have a priority on domestic hot water.
In this case the pump of the heating circuit will be stopped to keep the priority on the domestic hot water.
Note:
- The heating output will stay activated even if the aquastat have stopped the circulation pump.
- To avoid problem in cooling mode, if the storage tank is filled with cold water (by heat pump...) the
aquastat function will be automaticallydesactivated.

In case of mutizone regulation “WFHC Master RF with or without Heat&Cool function”is installed you
could use the input 1 to connect the pump relay output to swtich off the circulation pump1 in case of no
water circulation demand is asked in the house.
Note:
- The heating output will follow the circulation demand from the pump1.
5.5.2 Input2
Inst: System parameters: Input, “HC”
You could use the input 2 to connect the an external signal which give the Heating or Coling working mode
of the installation (This signal could be done directly by a reversible input).
“HC” is only available if Input1 is set on “no or Aqua”
Inst: System parameters: Input, “Aqu”
You could use the input 2 to connect the an immersion thermostat witch schould be placed in a storage
tank. In Heating mode this immersion thermostat will be use to switch off the circulation pump to avoid cold
water circulation in the circuit if the storage tank is discharged.
The immersion thermostat connected on the Input2 will manage the working of the main circula-
tion pump (Mixed circuit) if the ClimaticControl-HC drive only one pump.
In the installation with two circulations pumps, the immersion thermostat connected on the Input2
will manage the working of the 2nd circulation pump (direct circuit).
Note:
- The heating output will stay activated even if the aquastat have stopped the circulation pump.
- To avoid problem in cooling mode, if the storage tank is filled with cold water (by heat pump...) the
aquastat function will be automaticallydesactivated.
Inst: System parameters: Input, “C_b”
In case of mutizone regulation “WFHC Master RF with Heat&Coolfunction”is installed you could use the
input 2 to connect the pump relay output to swtich off the circulation pump in case of no circulation demand
is asked in the house.
The WFHC connecting box connected on the Input2 will manage the working of the main circula-
tion pump (Mixed circuit) if the ClimaticControl-HC drive only one pump.
In the installation with two circulations pumps, the WFHC connecting box connected on the Input2
will manage the working of the 2nd circulation pump (direct circuit).

6 Types of operating modes / Program menu
6.1 Types of operating modes
Selection of the operating mode is done using the arrow keys (◄) and (►). The cursor must be positioned on the
symbol of the relevant operating mode.
COMFORT mode of operation
Unlimited operation in COMFORT mode .
The system runs in constant comfort mode. The ClimaticControl-HC adjusts the flow temperature depend-
ing on the outdoor temperatureand the selected curve. No temperature setback.
The display Pos. 5 shows the current flow temperature and the outside temperature at 13 (damped val-
ue). By pressing the button (OK) the preset value of flow temperature appears for about 3 seconds at 5 . At
the same time the manually selectable deviation is displayed at 13 (factorysetup: 00.0 = no deviation).
Using the buttons (+) or (-) you can adjust the preset value of the flow temperature. If changed, the sym-
bol appears on the display.
In heating mode of operation if no room thermostat is installed ( MuB: 5.3), the circulation pump is
running continuously. The pump switches off if the mixing 3 way valve is closed for the setting time
(PUMP: System parameters: pump delaytime). That is the case when the room heating is sufficient
and the room thermostat closes all heating circuits by means of actuators. The same happens when the
value of flow temperature calculated by the ClimaticControl-HCbecomes lower than the actual tempera-
ture value because of rising outdoor temperatures. If the actual value of the flow temperature falls below
the preset value, the pump will restart.
In this case to ensure a correct measure of the water temperature the pump will be start each 30min
for a short time to measure the real temperature of water inside the hydraulic circuit.
To ensure energy saving operating mode of the pump it could be switched by a “pump logic”of a elec-
tric connecting box. The connecting box is normallyused together with room thermostats and electro-
thermic actuators. The “pump logic”is a potential free switching relay, the contact of which is closed
whenever higher temperature is demanded in any of the rooms. If all rooms are warm enough, the contact
opens and the pump turns off. ( MuB: 5.5)
If the heat generator / boiler (WE) is in temperature setback and the temperature supplied by the WE
is below the preset temperature calculated by the ClimaticControl-HC,heating mode is not available.
However if the circulation pump is actuallyrunning and the 2/3-way valve may also be opened by the 3-
point actuator because of room heating demand, the preset value of flow temperature may be exceeded for
a short period of time when the WE switches to heating mode. In this case, if a temperature limiter is
available, the pump might switch off and then pump operation will be possible only after the temperature
drops below the preset maximum temperature of the TB.
Trouble-shooting: The TB should be installed at a greater distance from the control unit. If necessary you
can set the TB to a higher temperature until the pump starts. After a few minutes of pump operation the
maximum allowable temperature set on the TB should be restored. Alternatively you can remove the TB
from the pipe for a while and leave the pump running for a few minutes. Then refit the TB again to the
pipe.
AUTOMATIC mode of operation
Automatic mode of operation using the built-in or user programs.
The ClimaticControl-HCis controlled according to the selected built-in or user program (6.2.).
The flow temperature is controlled depending on the outdoor temperature and the curve with room com-
pensation if RF thermostat is installed. (5.3.3 –5.3.5).
The room compensation function will be different depending of the RF thermostat installed:
* With WFHTRF-BASIC or LCD (Non programmable thermostat)
The room temperature compensation will be taken in account only during Comfort period of the pro-
gram. During the Reduced period the Water temperature will follow the curve minus the temperature
setback offset.

13
GB
* With MILUX RF (Programmablethermostat)
The room temperature compensation will be taken in account during Comfort and Reduced period
of the program. In this case the program of the MILUX RF should be the same of the water program ad-
justed on the CC-HC to have the best optimising energy consumption (the water temperature will be re-
duced due to the CC-HC program (in ) and by the setting temperature reduced also in the room due to
the MILUX RF program.
* With MILUX-RF HYGROSTAT (Programmable Heat and Cool thermostat with Humidity supervising)
The program will be now done on the MILUX-RF HYGROSTAT (Program made on Zone1 see the user
guide of the MILUX-RF HYGROSTAT for more explanation).
The room temperature compensation will be taken in account during Comfort and Reduced period
of the MILUX-RF HYGROSTAT program.
The Comfort and Reduced manual offsets added or subtracted to the calculated water temperature will be
always adjusted on the both working mode of the CC-HC ( 0.00°C & -10.0°C by default).
For the operation of the circulation pump please refer to the section of COMFORT mode of operation.
REDUCED TEMPERATURE mode of operation
Unlimited operation in REDUCED TEMPERATUREmode .
This is a constant mode of operation of the system. The ClimaticControl-HCadjusts the flow temperature
continuously on the basis of outdoor temperature and the selected curve and substracting the value of
temperature setback (factorysetting -10.0 К in Heating mode & +3.0 Кin Cooling mode).
The display indicates the current flow temperature at 5 and the outside temperature at 13. By pressing the
button (OK) the preset value for the supply flow temperature reduced by the setback in temperature is
displayed at 5 for 3 seconds. Simultaneouslythe reducing difference appears in 13 (without deviation =
-10.0). It can be changed by the buttons (+) or (-).
For the operation of the circulation pump please refer to the section of COMFORT mode of operation.
See the previous part for more explanation concerning the room compensation function when RF
thermostat is installed.
ABSENCE/VACATIONmode of operation
Time-limited operation of REDUCED TEMPERTURE mode .
Duration can be set between 1 and 24 hours and up to a maximum of 44 days. When this period is ex-
pired the ClimaticControl-HC switches back to operating mode .
By means of the arrow keys (◄) the cursor is first moved to . Then appears on the display at 13.
The duration of absence can be changed using buttons (+) or (-).
Example: = 1 hour; = 1 day
Both symbols and start blinking. The remaining time is displayed at 13.
To discontinue this mode of operation before time you have to set the remaining time at 13 to using
the (-) key.
STOP mode
This mode is used to switch off the system.
The device switches off the system. The ClimaticControl-HCsoftware version is indicated on the display
for about 3 seconds and then switches off (no indications).
By pressing any of the keys the ClimaticControl-HCcan be switched on.
REMARK: When the ClimaticControl-HCis in STOP mode,
In Heating mode only an Anti-freeze function can restart heat relay and circulation pump to maintain the
water temperature above 10°C.

14
GB
Heat & Cool Mode
Use this mode to change the working mode of your installation, Heating or cooling mode.
This mode will be only displayed if:
- The CC-HC is configured to manage a reversible installation (Inst: Parameters menu: Type, “Rev”)
- No MILUX-RF HYGROSTAT is installed (5.3.4) and configured to manage the Heat and Cool mode.
- No CC-HC inputs (In1 or In2) have chosen for a H_C signal input. (5.5)
Carfull:
IF Heat pump or other system is used and not linked with the ClimaticControl-HC, pay attention to change
the working mode on it before change on the ClimaticControl-HC. Because in this case the regulation will
not work in the correct way.
